JOSEPH J. HALL, OF LOS ANGELES, CALIFORNIA, ASSIGN OR, BY MESNEASSIGNMENTS, TO JAMES SMITH, OF PASADENA, CALIFORNIA.

MINERAL-ou. BURNER.

SPECIFICATION forming part of Letters Patent No. 593,801,dated November16, 1897.

Application iiled April 14, 1896.

To all whom it may concern.-

Be it known that I, JOSEPH J. HALL, a citizen of the United States,residing at the city of Los Angeles, in the county of Los Angeles andState of California, have invented certain new and useful Improvementsin Burners for Burning Mineral Oils, of whichthe following is a full,clear, and exact description or speciication, reference being had to theannexed sheet of drawings, and to the letters marked thereon. v

The object of my invention is to burn oils of the class known as mineraloilseconomically and without the production of smoke. According to myinvention I carry out this object by an apparatus whereinto the oil iscaused to drop in a regulated quantity into a hollow'or gutter aroundthe upper part of a mixing-chamber. The mixing-chamber is suspended in aframe and depends for a sufflcient distance down into the fire-box of astove, lire-grate, or other heating apparatus whereto. my invention isapplied.- The draft through the chimney or flue of the stove or otherappliance or apparatus causes air at all times to be drawn from theouter atmosphere ldownthrough an opening Vin a lid into themixing-chamber, wherein this air mixes with the vapor from the oil inthe gutter inits descent through the mixing-chamber, while another partof the air passing through openings in the lid descends through theconical annular space surrounding themixing-chamber, but does not burnuntil it issues from the bottom of the conical space, where it meets theoutside of the iiame produced by the vapors from the oil and airdescending through the mixing-chamber, thus producing intense heat atthe point where the air issuing from the surrounding conical space meetsit, so that the full heat d ue to the combustion is developed in there-box of the stove, fire-grate, or other heating apparatus whereto myinvention is applied. l

On the annexed sheet of drawings., Figure l is a vertical section of myimproved mineral-oil burner, showing allthe parts as they are situatedin relation to each other when in action. Fig. 2 is a plan of the same.Fig. 3 is an elevation showing my apparatus applied to a heating-stoveand in action. Fig. 4 isa Serial No, 587,470. (No model.)

plan of the gutter and mixing-chamber and the lugs whereby the gutterand mixing-chamber are suspended inthe frame, which rests uponthe topplate of the stove, fire-grate, or other heating appliances.

In the figures the mixing-chamber is marked A and may be of conicalform, as shown. The upper part of the mixing-chamber is formed with ,agutter B, and it is suspended in the conical frame I by means of thelugs J, which rest upon the inner part of t'he frame I. The oildischarge or feed pipe C drops the oil into the gutter B. As the severalparts constituting the burner are situated within the lirebox of thestove or other heating appliance, all parts thereof become hot, and theoil as it drops from the pipe O into the gutter B becomes immediatelyvaporized or'converted into gas, while the suction or draft produced bythe chimney D, Fig. 3, of the stove or other heating apparatus causessome of the air and thevaporfromthe oiltobecontinuouslypulled downthrough the central opening K in the lid G into the mixing-chamber A, asindicated by arrows in Figs. -1 and 2, thereby forming ahighly-combustible mixture, which on arriving at the discharge-orifice Emeets with the other parts of the hot air descending through theopenings H in the lid G and thence down through the conical space F, sothat these burn and develop intense heat within the lire-box of the saidstove or other heating appliance. As it is desirable that the quantityof oil used should be under control and Vexact-1y regulated, a regulatoror Valve (not shown in the drawings) is placed in the pipe between theoil and the burner, while the quantity of oil may be further adj ustedfrom time to time, as required, by means of aneedle-regulator, as iswell understood.

Having now described the nature of my said invention and the bestsystem, mode, or manner I am at present acquainted with for carrying thesame into practical effect, I desire to observe, in conclusion, thatwhat I consider to be novel and original, and therefore claim as theinvention to be secured to me by Letters Patent, is as follows:

A downward acting burner for burning mineral oils consisting of themixing-chamber the outer conical chamber surrounding the IOOmixing-chamber, the outer conical chamber gether in the manner and forthe purposes and mixing-chamber forming an air-heating substantially asset forth. space between them, the mixing chamber In testimony whereof Ihave hereunto set formed with the vapor-generator adapted to mysignature in the presence of two subscrib- 5 discharge into saidehamberat its top in Which ing Witnesses.
